Referring in detail to the drawing, the

numerals 1 and 2 illustrate parallel side frames which. are bolted to a bed of concrete or thelike thru the means 3, and at one end are provided with pillow blocks 4 in which a shaft 5 is cradled, this shaft being retained in position in the pillow blocks 4 by, caps 6. Upon said shaft aroll of. relatively tough but flexible paper is mounted,

said paper being fed to e gang dies thru a system of rolls which will be more fully hereinafter described.

The frames 1 and 2 support a shaft 7 at the ends opposite to the pillow blocks 4 and on this shaft a pulley wheel 8 is rigidly mounted intermediate its length. This shaft is retained in place by the caps 9, and the end whichextcnds from the frame 2 has a fly wheel 10' mounted thereon. The opbeing in continuous mesh with the spur gear 11. The frames 1 and 2 are provided with ledges 16 at various positions in order to support the foot plates 17 of additional frames 18 and 18, the foot plates of said frames being secured to the ledges 16 by bolts 19. These additional frames 18 and ,9 are provided with substantially U- guides 20,21 and .22 in which vers in annels are formed. The guides 20 and 21 are arranged side by side, and the guide 22- is positioned below the guide 21 The guide members 22 slidubly support the ends of spindles 24 and 25 on each of which a roller 26 and 27 is rigidly mounted, the

peripheries of. the rollers being normally retained in mutual yieldable contact. The roller 91 has approxin'iately half its periphery immersed in water which is contained in alongitudinzl tank 28, the latter being supported beneath the roller 27. The sheet material or a paper from'thc roll 29 is trained about part of the periphery of the roller 27 and rides between. the rollers 26 and 27, and its lower surface is moistened as the periphery of the roller 26 accomplishes this purpose; An additional roll 3 is mounted on a. shaft 31 at the corners of the frames 18 and 18, this roller supporting said paper or sheet material and also changes its. cour le so that after passing from the periphery of the roll to where it enters between the rolls 32 and 33, it reverses its surfaces so that the surface which was originally at the bottom is transposed and becomes the upper surface. The roll 33 mounted in the guides 21 lies beneath the rol 32 and a portion of its periphery is continually immersed. in a tank of water 34: in a similar manner as the roller 27. These guide members 29, 21 and 22, are provided with caps to prevent inadvertent pulling out of the shafts 24, 37, and 38, supporting their individual rolls, and the caps 35 surmounting and bolted to the guide members 20 and 821 are provided with springs 36 which urge the shafts 37' and 38 downwardly so that the peripheries of the rolls 32 and 42 mounted on these shafts will movably contact with the peripheries of the lower rolls.

33 and 39, the. latter two. rolls being mounted in spindles-40 and irk-respectively. The rolls and 42, the latter being mounted above the roll 39, serve as friction rolls for feeding the paper toward the gang dies. The shaft 41 on which the roll 39 is mounted, has an end which extends beyond the frameflitl andto said end a bevel gear 43 is secured, this bevel gear bcing in mesh with an additional gear -14; which is mounted on a shaft 45. The latter constitutes a rotatable vertical men'ibcr journalle'd near its upper and lower ends in extension of the frame 18'' and has a friction pulley '46 mounted on its lower end. This friction pulley is slidahie longitudinally on the shaft 45 and provided with a sleeve 47 which rigid with the pulley and is secured to the shaft by a rew 43. A stud 4:9 extends from the Zowe. arm of the frame 18 in a horizontal direction and rotatably supports a disk .5") on which a friction surface 51 is Pl'UYldPfj, the peri liery of. the pulley 46 provided uith friction material set being also in order to insure f ictional contact at all times with the ace [ii of the disk 50. The stud 49 which supports the disk. 50 has a s n-ticket wheel r' 'idly seciu'eihthercon between the disk 59 and the frame 18 and is connected thru a sprocket chain 53 to the 'rotatably support shafts 56 mounted on the frames being rotatable thru a knob 77'.

sprocket wheel 1-1, the latter being rigidly mounted on the end of the shaft 12.

Upper horizontal guide arms 54 and lower guide arms 55 are provided on the main frames 1 and 2, the arms 54-- being directly superimposed over the arms 55. The guide channels between the upper arms and 57 upon which parallel and adjacent feeding rolls 58 and 59 are mounted. These shafts 56 and 57 extend slightly beyond the. frame 2, the extending end of the shaft 56 being provided with a gear 60, while the opposite shaft 57 has a gear 61 secured thereon which meshes with the gear 60, the shaft supporting said gear 61 also having a sprocket wheel 621 rigidly mounted thereon. The channel between the arms 55ion the lower portion of the frame rotatably support a pair of shafts 63 and 64 which have rolls 65 and 66, respectively, mounted thereon. The rolls mounted on the shafts 56, 57,- 63, and '64, have their peripheries retained in yieldable position by the caps 67 beneath which coil springs 68 are mounted. The roll 65 is in synchronous rotation with its upper roll 59 thru a bevel gear attached to the end of the shaft 63 which extends beyond the frame 2, the sprocket wheel 63 on the shaft 63 being connected to the sprocket wheel 62 by a sprocket chain 69. These rolls 58, 59, 65, and 66, are actuated independently of the remainder of the feeding mechanism 18 and 18 and have a movement which serves to intermittently rotate the rolls, the linear distance of movement being equal to the diameter of the blank to be punched from the sheet material. This intermittent movementof the rolls 58 and 59 is accomplished thru a crank mechanism which comprises a cap 70 rigid with the shaft-12 which extends from the frame 1,and an eccentric stud 71 extending from this cap is joined to one end of a rod 72. The opposite end of this rod 72 is secured to a stud 73, the-latter being mounted on a disk 74 off-set from its rotational axis. Guide bars 75 are rigidly mounted on the face of this disk and have cap plates secured to their end which rotatably retain a this threaded stud A block is slidahlc between the bars 75 and has a threaded opening in which the screw stud 76 is engaged. A pin 79 extends from one side of the block 78 and has one end of a rocker arm 80 connected thereto. This rocker arm extends angularly upward and has its upper end formed into a rack 81 whose teeth engage a gear 82 rotatably mounted on the end of the shaft 57 which extends from the frame 1. A ratchet wheel threaded stud 76 in place,

83 is rigidly mounted-0n the shaft 57 between the gear 82 and the face of the frame 1. One face of the gear 82 has a pin 84 projecting therefrom on which a awl 85' is mounted the pawl being engages is with the teeth 0 the ratchet 83 to accomplish intermittent rotation of the shaft 57 and the roll 59. An extension 86 of the upper guide bar 54 has a round -headed plunger 87 mounted therein which is extended by a coilspring 88 within a chamber in said extension. face of the rack 81 and urges the teeth of the same into mesh with the teeth of the gear 82. j j

Recesses are formed in both frames 1 and 2 between arms 5d and and receive the bed plate 89 of the gang dies. The bed plate of the gang dies is retained in lace by passingrlgbetts 90 thru the ends. hese bolts areshnm'idered and supported at'their opposite earls one triangular bracket 91. 1e bolts extend in a horizontal direction iaind are shouldered where one end passes thru the bed plate of the gang die and is secured in place by suitable nuts. The remaining lengths of these bolts between: the bed plate 89 and the triangular bracket 91 are exposedand support a movable punch head 92 in which the gang punches are mounted. The rear face of the movable punch 92 is provided with spaced-apart cars 93 near both of its ends-between which one end of the eccentric rods 94: are mounted, these eccentric rods being in enga ement with a. pair of eccentrics 95' lyingadjacent to the adjacent sides of the frames 1 and 2. By virtue of the eccentrics 95, the movable head 92 is capable of bcinghorizontally actuatcd thru a slight distance when the machine is 111 operation. the bed plate 89' comprise a lon 'itudinal body 96 which extends horizontally across the width of the machine'and is secured on the bed plate by bolts 97. Theshearing die for cutting the blanks from the sheet material comprise an annular flanged collar 98 whose internal periphery 99 presents the shearing edge, the shearing edge on said die being raised above the face oi the body 96. The portion of the body adjacent the internal periphery 99 has av convexly curved surface 100 which extends toward the center- The members 98 are aligned in a horizontal plane and in this machine are shown to the number of eight, eachof-these members 9h being identically constructed. WVitlr in each oi the collars 98, a flange 101 is slidably mounted in a recess 102, the flange having a' concave face 103 on one side, the side opposite to this face having a stud 101 on which a spring 105 is mounted. A nut 106 on the threaded end of the stud 104 latter is retained spring 105.

The forin the shank 107. This stem passes entirely thru the shank and has an eye 113 at is opposite end. head is provided with a shoiilder 114 having the'identical curvature as the portion 100 of The face of the plunger head is concaved as indicated bythe'numeral 115 and is adapted. to provide a seat for a floating punch 116 Whose face 117 has a convex curvature the same as the concave curvature 103 on member 101. .This floating punch 116 has a, stud 118 slidably mounted in the forming punch and is retained in place by a pin 119 and normally extended by a spring 120, the latter being housed in a-rccess formed in the head 111-. The eyes 113 which are eight in number are all mounted on a common shaft 121 which is in turn joined to a connecting'arm 122. In order to permit adjustment of the lengtlrof the eccentric arms actuating the shaft 121, a, novel fea ture is incorporated. This comprises a plurality of blocks 123v which are mounted on the shaft 121. Theienlarged end 124s of the arm 122 receives these blocks whichin addition has'vertical tapering channelsdn which The outer end of the forming a I wedges 125 aremounted, it being noted that each arm base pair of channels, the taper- -ing face of each pair of channels being: on

opposite sides of the same. These wedges are surmounted by 'studswith which nuts are 'engageable. By drawing down one of these wedge blocks and loosening the opposite one, a longitudinal displacement of the block 123 becomes possible, thus increasing and decreasing. the length of the arm. The arms 122 constitute solid-bars substant y circular in cross fse'ction. 'At a position 'intem mediate their length threads 126 areformed which engacc a nut 127. This nut shoulders within a hollow arm 128. The latter has an opening 129 formed therein. in which a reduced and 13 of the arm 122 is slidable. A collar 131 is slidablymounted on the red-need end of the arm 122-and between this collar,

and member 127, a spring 132 is mounted, the latter by engaging the collar 127 fixed to the arm 122, causes the latter to be urged outwardly. The, rear end o'idniember 128 is formed into a cradle133 in which a semicircular opening-isformed, This opening is flanged and is covered by a similar shaped scmi circular strap. 134. thus providing an fliinular'opening in which an eccentric disk will then he at ihe 135 is rotatable, thie eeeentric dish being rigidly mounted on the shaft 'lf'heprorluct formed with this machine is shown in cross section in Figure-9 in which is illustrated a crown v.
